摘要： A device for synchronizing the tilt of the backrest and of the seat of a chair, of the type having a frame of the backrest, a frame of the seat and a support integral with the base of the chair, as well as a first crank, integral with the backrest frame, and hinged in the rear portion of the seat frame and the support, and at least one second crank hinged in the front portion of the seat frame and to the support. The first crank and the second crank (5) form, together with the seat frame, a four-bar linkage. An adjusting lever is constrained to the four-bar linkage and is further operatively connected to a movable fulcrum and elastic means.

摘要： A device for adjusting the tilt of a chair backrest having a backrest frame rotatable with respect to the base frame of the chair is provided. The device includes elastic means for returning the backrest and/or countering the rotation thereof, in addition to means for controlling the preload of the elastic means. The means for controlling the preload include at least one first connecting rod and at least one first crank. The first connecting rod is hinged to the first crank and constrained to the elastic means so as to move the point of application of the returning and/or countering force with respect to the backrest. Adjusting means to adjust the position of the first crank determine at least two distinct stable positions of the first crank corresponding to two distinct positions of the mentioned point of application of the returning and/or countering force with respect to the base frame.

摘要： A mechanism for adjusting the seat of a chair as a result of changing the tilt of the backrest with respect to the seat is provided. The mechanism has a backrest frame and a base frame, as well as a covering element stably combined with the base frame and forming part of the seat. The backrest frame is rotatably constrained to the base frame around a respective rotation axis and tilting with respect to the seat between a position (P1) of minimum tilt and a position (P2) of maximum tilt. Advantageously, the covering element is partially elastically deformable, with the mechanism having deforming means operated by the backrest frame in order to reversibly deform, in the vertical direction, when the covering element as a function of the tilt angle with backrest frame has reached with respect to the position (P1) of minimum tilt.
